针对传统小波变换法去除干式空心电抗器红外图像中夹带的噪声效果不理想的问题,提出了基于改进小波变换与卷积神经网络的干式空心电抗器红外图像去噪方法。首先利用卷积神经网络中的残差学习对图像中混合特征信息进行提取;然后通过改进小波变换对图像进行小波分解,并将分解后的分量输入至网络中进行训练;进而通过残差学习增强图像纹理细节信息,解决了传统图像去噪方法的不足;最后进行仿真比较。结果表明,所提方法可以降低网络计算难度,加快训练速度,同时具有良好的去噪性能,优于传统图像去噪方法。

As a kind of important new capital form,agricultural ecological capital plays a decisive role in guaranteeing healthy development of agricultural ecological economy. Therefore scientific understanding agricultural ecological capital is favorable for developing agricultural ecological economy,while clarifying factor structure,value assessment and accumulation mechanism of agricultural ecological capital is important content of understanding agricultural ecological capital. In this paper,factor structure of agricultural ecological capital is firstly elaborated,and it is thought that agricultural ecological capital is the unity of agricultural ecological environment,agricultural ecological resource and agricultural ecological system. Then agricultural ecological capital value is assessed according to use value method and non use value method,thereby realizing quantification of agricultural ecological capital. After agricultural ecological capital passes through value assessment,the value is more clear,which creates condition for agricultural ecological capital accumulation. Finally accumulation mechanism of agricultural ecological capital is analyzed. Accumulation channel of agricultural ecological capital is explored from natural and human factors,and it is found that agricultural ecological capital accumulates in the forms of agricultural ecological restoration and agricultural ecological compensation.

The capitalization of agricultural land as an institutional innovation in land use is of great significance to revitalize China's land resources, change land use and improve land use efficiency. With the gradual implementation of the capitalization of agricultural land, however, environmental problems brought by capitalization have restricted the sustainable and efficient utilization of agricultural land. This study, from the perspective of ecology, discusses ecological risks of agricultural land capitalization, analyzes the ecological risks of agricultural land capitalization in terms of the amount of land and land quality as well as the formation mechanism of the ecological risks of agricultural land capitalization. It is found that the logic of the capital itself, the profitability of the subject and the fragility of the ecological environment are the internal and external factors of the ecological risks of agricultural land. Thereupon authors put forward policy suggestions to prevent the ecological risks of agricultural land capitalization in terms of large-scale agricultural operations in diverse forms, the development of green agriculture, the protection of agricultural land quality and green finance, with a view to resolving the ecological risks of agricultural land capitalization and realizing the benign operation of agricultural land capitalization.

数据在当今社会中扮演了重要角色,影响着政治、经济、文化等方面的发展。近年来,对数据权利的研究蓬勃发展,逐步明确了数据权利包含人格权、财产权、国家主权三大类权利的基本趋势。虽然有此趋势,但是研究过程中仍然存在着权利研究相互割裂,缺乏联系,没有形成数据权利内部统一价值标准与规则的问题。应当借以"权利束"这一概念,通过有效"束点",确定"权利边界"的方法,以数据权利束的视角对数据权利进行研究。明确其以数据权利为基础,集合多元主体、多种权利的事实。规范数据权利束内的权利组成与权利边界,阐明数据权利束的价值内涵。以数据权利束的价值内涵和权利价值观作为指导,形成数据权利束内在权利位阶,以此形成一种数据权利束确权、归集与保护之范式。

The study of sedimentary mélanges holds pivotal importance in understanding orogenic processes and unveiling geodynamic mechanisms. In this study, we present findings on zircon U-Pb isotopes and whole-rock elemental data concerning the recently uncovered Zongzhuo Formation sedimentary mélanges within the Dingri area. Field observations reveal the predominant composition of the Zongzhuo Formation, characterized by a matrix of sandstone-mudstone mixed with sand-conglomerates within native blocks exhibiting soft sediment deformation. Moreover, exotic blocks originating from littoral–neritic seas display evidence of landslide deformation. Our study identifies the depositional environment of the Zongzhuo Formation in Dingri as a slope turbidite fan, with its provenance traced back to the passive continental margin. Notably, this contrasts with the Zongzhuo Formation found in the Jiangzi–Langkazi area. Based on existing data, we conclude that the Zongzhuo Formation in the Dingri area was influenced by the Dingri–Gamba fault and emerged within a fault basin of the passive continental margin due to Neo-Tethys oceanic subduction during the Late Cretaceous period. Its provenance can be attributed to the littoral–neritic sea of the northern Tethys Himalaya region. This study holds significant implications for understanding the tectonic evolution of Tethys Himalaya and for reevaluating the activity of the Dingri–Gamba fault, as it controls the active deposition of the Zongzhuo Formation.

With the promotion of agricultural ecological civilization construction in China, agricultural ecological security has received increasing attention. How to ensure agricultural ecological security has become a great concern for many scholars. As an important agricultural province in China, Hubei is of great significance to Chinese food security and agricultural sustainable development. This paper aims to establish an index system of agricultural ecological security and security classification of Hubei via Analytic Hierarchy Process and Pressure-State-Response methods. An evaluation of agricultural ecological security in Hubei, with a base of the national average value in 2015, reveals that the security degree has increased by 0.07566 from 0.90150 in 2005 to 0.97716 in 2015. Results show that agricultural ecological security in Hubei has improved but failed to reach the national average and there is still large space for improvement of the security level, considering a trend of deterioration in some indexes, such as per capita water resources, population density, per unit area pesticide load of farmland, forest coverage, grassland degradation rate and average annual precipitation. Influencing factors, especially population spatial distribution, misconduct in agricultural production, insufficient ability in agricultural natural disaster prevention, deficiency of agro-ecological technology of agricultural ecological security in Hubei are analyzed. For improvement of the degree of agricultural ecological security in Hubei, some countermeasures and suggestions are discussed.
